Embodiment Construction

[0034] The present invention is mainly composed of a main control module, a power supply module, a sensor module, a display module, an alarm module, a button module and a memory storage module. The mass change calculates the liquid medicine flow rate, and then calculates the remaining time of the infusion.

[0035] The main control module is composed of STC12C5A60S2 single-chip microcomputer and its basic peripheral circuits. It uses an external crystal oscillator with a frequency of 11.0592Mhz, and realizes information interaction with other modules through the GPIO port;

[0036] The power module is composed of two AAA dry batteries, MCC6288 boost circuit and power switch, which can output a stable 5V voltage to supply power for microcontrollers and sensors;

[0037] The sensor module is composed of a tension sensor with a range of 3kg and an HX711 conditioning circuit, and the voltage value linearly related to the quality is input to the microcontroller through the I2C bus;...

Abstract

The invention relates to an infusion alarm with time display function and a program control method thereof. The alarm is powered via two No. 5 dry batteries and has no need for an external power supply, and it is convenient to use the alarm just after the upper end of the alarm is suspended to an infusion stand and a medicine bottle is suspended to the lower end. When a patient takes drip infusion, such alarm displays infusion remaining time in real time through a digital tube and provides buzzer alarming when liquid medicine is about to be run out. STC12 single-chip microcomputer is used herein as a master control chip, weight of the medicine bottle is acquired through a tension sensor, and effective data information is acquired via data transformation, processing, and filtering of invalid data. The single-chip microcomputer calculates a flow speed of liquid medicine according to variations in the weight of the medicine bottle, thereby calculating infusion remaining time.

Description

technical field [0001] The invention specifically relates to a medical infusion alarm based on single-chip microcomputer control and a program control method thereof, belonging to the technical field of medical equipment. Background technique [0002] Drip infusion has the advantages of direct administration, fast onset of action, and many types of applicable diseases, and has become one of the main medical treatment methods. Nowadays, the total annual infusion volume in our country has reached more than 10 billion bottles. With the aggravation of population aging and other problems, the domestic demand for infusion will continue to increase, and accordingly, the optimization and upgrading of infusion-related devices and equipment will also change. become more and more necessary. [0003] Nowadays, patients, especially elderly patients, often need their children and relatives to accompany them during infusion, and pay attention to the remaining amount of liquid medicine in ...
